The Sonic Hedgehog (Shh) gene expresses a highly conserved signalling molecule essential for cell-to-cell communication, which regulates key biological processes, such as embryonic development (as embryo days; ED) and organogenesis.

In this study, 150 fertilised Jilin white goose eggs were analysed to investigate embryonic skin morphological changes. Immunohistochemistry (IHC) was applied to determine the localisation of Shh protein, while qPCR and Western blotting were conducted to examine the temporal dynamics of mRNA and protein expression.3.

In total, 1012 one-d-old male chicks were assigned to one of six treatments, each with a minimum of seven replicates in a randomised incomplete block design.

On d 12, except for C-NCH, all birds were inoculated with mixed <i>Eimeria</i> spp. oocysts through feed to induce enteric stress.

Treatments included vitamin C levels of 0, 100, 200, 300 or 400 mg/kg, respectively.3. Dietary vitamin C supplementation led to a highly significant linear increase in laying rate (<i>p</i> < 0.01), with significant improvements detected at 300 mg/kg and 400 mg/kg (<i>p</i> < 0.01). Thus, within the supplement range of 0-400 mg/kg, graded additions of vitamin C linearly improved reproductive performance with economic benefits. In consideration of commercial breeding practices together with the observed physiological and productive indices, dietary vitamin C supplementation at 300 mg/kg was effective.4. Feeding 300 mg/kg prompted oestradiol and progesterone concentrations in both serum and hierarchical follicular yolks (<i>p</i> < 0.05) and the number of primordial follicles increased significantly (<i>p</i> < 0.01). This level of vitamin C in the feed resulted in elevated activity levels of total antioxidant capacity, superoxide dismutase and catalase in both serum and follicles, along with a reduction in malondialdehyde levels.5.

In this study, the combined sanitising effects of sodium hypochlorite (NaClO) and carbon dioxide microbubbles (CO<sub>2</sub>MB) on artificially applied EC on eggshells were clarified and the effectiveness for sanitising fertilised eggs was investigated.2. The number of surviving EC cells on eggshells decreased with increasing chlorine concentration and treatment time, with the NaClO solution containing CO<sub>2</sub>MB. The spray treatment of the NaClO solution containing CO<sub>2</sub>MB was more effective for sanitising EC.3. In addition, sanitisation of EC on fertilised eggs using a NaClO solution containing CO<sub>2</sub>MB was effective in preventing contamination in the setter, without negative effects on hatching or early growth of chicks.4.
